From my own experience, this IS the best YouTube video downloader, so far, there are no other competitors. It is simple, functional and practical. From download to conversion every feature runs perfectly. Lately there was an issue with some downloads (my assumption, that it might have been due to the owners of Youtube), but soon enough an update was provided and fixed it, demonstrating the care, affection, and professionalism users get from the developer. Simply, I recommend this add-on as a MUST, above all other video downloaders.

uma das unicas a funcionar , obrigado desenvolvedores!

I have been using this add on for past few years most trusting add on

You just made my daughter a very happy little girl :)

5 stars praise! I have been using it very well, but now some videos prompt me "signaturelocal: cannot resolve signature; 3", I don't understand why, I hope to solve it soon!

Good

signatureLocal: cannot resolve signature;3

Was awesome, now it does not work at all. I'm sure it will be updated so keeping the 5 star rating, for now.
Not a new problem, YT changes stuff all the time. This developer keeps changing his app to comply with the changes.

Thank you so much. I was finally able to download a youtube video. I tried other down loaders but they didn't work.

everything works just fine, best YT downloader I've tried so far
